I hope this does not spell the end of UBERx (http://blog.uber.com/2012/07/03/sf-vehicle-choice/). As of right now, I can still see UBERx cars on the map so I have my fingers crossed.

Definitely not - UBERx is still going strong and we'll keep adding cars to it. We just didn't want to confuse people by lumping X/Taxi into one post.
